Evaluating the solution with imported geometry
The best evaluation of your solution is to set an object in front of the solved
camera and see if it matches the background as you play the animation. In
this case, we will import a fence modeled in Maya.
Before you load the modeled fence, do the following steps to add one more
survey constraint. You add a Point constraint to orient the solution so
fenceCorner is at the origin. You need fenceCorner at the origin because the
fence model has its corner at the origin and you want the two to match exactly.
To reorient the solution with fenceCorner at the origin
1 Switch to the Survey settings.
2 Choose Points from the Constraint Type menu.
3 Select the following track point in the Outliner under
clip1TrackedPointVisibilityGroup > clip1TrackedPointGroup:
fenceCorner
4 Click Create. Maya creates a Point constraint in your scene, located at
the origin (0,0,0) by default.
5 Switch to the Solve control panel, select registered1 from the solution
list, and click the Register button. The solver creates registered2 with
fenceCorner at the origin.
You will now import a fence that has been modeled to exactly match the fence
that was filmed.
